Answer:
1.087L
Explanation:
No of mole = concentrate × volume
Volume= 0.25/0.23 = 1.087L
Answer:
Keq=0.866
Explanation:
Hello,
In this case, the undergone chemical reaction is:
In such a way, since 0.0055 mol of N₂O₄ remains in the flask, one infers that the reacted amount () was:
In addition, the produced amount of NO₂ is:
Finally, considering the flask's volume, the equilibrium constant is then computed as follows:
Best regards.
Answer:
a. evaporation
.
Explanation:
In this case, given the described situation, we should take into account that there are two types of liquid-gas phase transitions, evaporation and vaporization, which occur in totally different way.
Firstly, evaporation is a superficial phenomena, it means that it occurs at the surface of the liquid only whereas the vaporization is a bulk phenomena, which means that it occurs along the whole volume of liquid.
In such a way, we can infer that cold steam stream flowing over the pond has the capacity to strip or remove liquid water molecules in the pond and take them to the vapor phase, which means that the answer is a. evaporation
.
Best regards.
Answer:
When you make coffee, some of the compounds from the ground coffee end up in the water, giving it the distinctive color, aroma, and flavor that we associate with coffee. The solubility of some coffee constituents varies depending on the temperature of the water.
